Description

The AC3overDVB patch for VDR sends digital audio data in AC3 and DTS format to the digital S/PDIF port of the DVB card. Therewith VDR has the ability to output Dolby Digital as optical or electrical S/PDIF signal.

The digital S/PDIF port of the DVB cards is only capable of sending PCM data, so the AC3 data has to be encapsulated into a PCM stream. This digital audio data stream is then received and decoded by a external Dolby Digital receiver.
